Current Electricity Part 4

Two cells of emfs 1 V and 2 V and internal resistances 2Ω and 1Ω, respectively, are connected in series with an external resistance of 6Ω. The total current in the circuit is l1. Now the same two cells in parallel configuration are connected to same external resistance. In this case, the total current drawn is l2.
